  2. 1. Wooded or treeless pastures? : Linking policy, farmers' decisions and biodiversity

    Author : Simon Jakobsson; Regina Lindborg; Sara A O Cousins; Jan Plue; Tim Benton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bat; biodiversity; bird; canopy cover; Common Agricultural Policy; European Union; farmer; functional diversity; germination; grassland; multi-taxa; pasture; plant; policy; seed sowing; tree density; trees; Physical Geography; naturgeografi;

    Abstract : Worldwide, biodiversity conservation is one of the key challenges for a sustainable future of nature and society. It is particularly important to preserve high quality habitats within otherwise intensively managed agricultural landscapes. READ MORE

  4. 2. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter

    Author : Martin Andersson; Eva Lindström; Stuart Jones; Uppsala universitet; []
    Keywords : Dissolved organic matter; BCC; biodiversity; functional redundancy; Mikrobiologi; Microbiology;

    Abstract : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop.

  5. 3. Biodiversity patterns and the processes regulating them along elevation gradients in the Swedish mountains

    Author : Johannes Måsviken; Love Dalén; Anne Bjorkman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; elevation gradients; spiders; insects; plants; latitude; altitude; alpha diversity; beta diversity; taxonomic diversity; phylogenetic diversity; functional diversity; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Biodiversity describes the total variation of life and includes the taxonomic, genetic, and phenotypic differences among organisms. Variations of biodiversity in space and time may be driven by ecological, evolutionary, or neutral processes. READ MORE

  6. 4. Effects of Past and Current Land Use on Biodiversity: from a semi-natural grassland on Öland (Sweden) to a European perspective

    Author : Marie Vandewalle; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ecosystem services; bioindicators; land-use history; Biodiversity; semi-natural grasslands conservation; habitat fragmentation; functional diversity;

    Abstract : Concerns are increasing about the loss of biodiversity under land use change and how this will affect the ecosystem services provided by natural and semi-natural communities and consequently how this will threaten human well-being. The thesis examines the impact of present and past land use on different aspects of biodiversity; namely species diversity, traits and functional diversity and on ecosystem services. READ MORE
